[Demon Cultivation]+ [Monkey Demon]+ [Demon Clan Perspective]+ [Traits]+ [Demon Sect]+ [Shadow God Painting]…
Chen Sheng transmigrates to a world much like Journey to the West, where he becomes a monkey demon patrolling the mountains and struggling to get by.
However, he gains the Shadow God Painting System, which lets him extract traits from the demons depicted in the painting.
[Extracted the “Wolf Archer” trait: Perfect Accuracy. Never misses a shot, even from a hundred paces]
[Extracted the “Ox Guardian” trait: Vigorous as a Dragon and Tiger. Boundless energy from now on]
[Extracted the “Erlang Shen” trait: Law of Heaven and Earth]
From then on, Chen Sheng sets out to dominate the demon world.
…
Many years later, Chen Sheng ascends to the heavens, frightening the celestial soldiers and generals into crying, “Oh no! The demon immortal who wreaked havoc in Heaven is back!”
The subject matter is good, good luck to the author
The wording and sentences are very much like Journey to the West.
It's well written and I can't find any loopholes.
